On the Bosch jobsite what brand speaker system is used in it.

Probably a bad solder joint or faulty control.

If it isn't on a tag on the bottom then it is likely missing.

there is no optical laser as a part for this.

In case of this kind of questions you can only advise someone to go back immediately where they have bought the tool for warranty or exchange or money back.

No other suggestions but few years to late to give the only right answer in this cause of question.

if you have short, maybe your have a IC amp short inside. You must go to the repair shop for fix it. The speaker you can test in another system.
God bless you

there are no adjustments on the movement you described. If this is a new saw as indicated I would return for warranty repair/replacement.

1) There is a big difference between Bosch promo manual and Bosch operation manual:

2) Online promo manual says: Combined Indirect/Pythagoras for measuring total height from a distance
http://www.boschtools.com/AboutBoschTools/RequestProductLiterature/Documents/2010%20Catalog%20PDF/2010%20Measuring%20Tools.pdf

3) Online operation manual shows no instructions for Pythagoras measuring.
And shows no button for displaying E value or height.

4) Operation manual shows:
Length Measurement** and tells you to measure the height while promo says tool will calculate height E
Area Measurement*** shows rectangle only and not triangle
Volume Measurement
Area or Volume
Rounding of Large Calculations
Continuous Measurement (Tracking)

5) I would contact Bosch directly:

6) Until you get satisfaction from Bosch, the Bosch device gives precise menasurements that can be entered into a Pythagorean calculator online, which defeats the purpose of a jobsite tool: But you can access online calculator via cell phone while on jobsite.

drop it off a 10 story building. It seems that all brands of jobsite radios are full of problems. On const. Sites I talk toowners of akl brands and almost all have problems. Bosch has most features but a little bib.

what causes that issue is that your treble and bass are probably turned all the way down. just adjust those up to max and your unit will be alot louder.
